SM 277C status LED can be used to diagnose the CANopen master-slave network.
Switch on the power of SM 277C, “ON” LED (Green) for the power would light on. If the BF and
SF LED remain OFF, indicate the SM 277C works normal, on or flash mean fault in hardware
configuration or wiring. If the main system running well, see table below for the reason for error:
